Comfort. Energy Expenses. Safety. Value

June 21 was the official first day of summer, but temperatures are already rising, especially in southern cities like Nashville.


If you’re ready to welcome the summer season with a new air conditioning system, you might want to know which type is the best fit for you and your property. You can choose from several different types of air conditioners, each with its own benefits and drawbacks.


Let’s explore the different air conditioning systems (and their pros and cons) so you can make an informed decision.

Central Air Conditioner

Central air conditioning units use split systems. They regulate air through ducts installed throughout your home, which is why they’re also known as ducted systems.


A central air conditioner is split into two primary units: the outdoor unit, which includes a condenser and compressor, and the indoor unit, which features evaporator coils and an air handler.


Central air conditioners use refrigerants to remove heat from the indoor air. So the heat gets pulled outdoors while cool air is pushed through your ductwork.

Smart Air Conditioner

A smart air conditioner is a type of mini-split (ductless AC that cools one part of the home), window (a unit that sits in the window and cools one area), or portable air conditioner (a movable unit that cools the area in which its plugged in).


Regardless of the type of air conditioner, smart units are Internet of Things (IoT) enabled, meaning they connect to your home’s wifi network. They also come with an app you can control through a smartphone or tablet.


With the app, you can schedule the unit to come on at certain times, adjust the temperature at certain times, etc.

Geothermal Air Conditioner

Geothermal air conditioners are some of the most energy-efficient units on the market today, using the earth’s natural insulating properties.


Four to six feet below ground, the temperature remains the same year-round, regardless of the weather up above. Geothermal technology utilizes this consistent temperature with pipes that move water through the home, the ground, and a heat pump.


The continuous circulation helps to adjust the temperature in the home, bringing in warm air from underground during cold seasons and transferring heat from the home during warm seasons.

How to Choose the Right AC System

Not sure which air conditioning system is best suited for your home? Here are some of the most important factors to keep in mind:

Energy Efficiency

Geothermal units typically use the least amount of electricity, making them the most energy-efficient options. Mini-splits are more of a middle-of-the-road option, and central air units use much more electricity, meaning you’ll spend more on utility bills with these systems.

Initial Investment

In general, a mini-split air conditioner will cost less to set up than a central air or geothermal unit (this type is the most expensive, although it can help you save money in the long run). If you have a tight budget, a mini-split may be the most cost-effective choice.

Cooling Capabilities

If you’re going to spend money on an air conditioning system, you want to know that it will genuinely cool your house and make it more comfortable. Geothermal and central air conditioners will cool a larger portion of your house at once, whereas mini-splits cool just one area because they don’t have any ductwork.
